Comparing the Risks of Climate Change and Geoengineering

C19 French Roberval Balance

The OSTP has adopted a ‘risk-risk’ framing in its report on geoengineering research: will this help or hinder sound climate policy?

Last month’s report on solar geoengineering research from the White House Office of Science and Technology Policy (OSTP) consolidated a shift in the discourse on this controversial technology. Over recent years advocates for more research have increasingly adopted a ‘risk-risk’ framing. As Gernot Wagner puts it in ‘Geoengineering: the Gamble’: “The decision is all about …

Not Just About the Climate

The benefits of the energy transition transcend climate.

The main reason to control carbon is to protect the climate. But cleaning up the energy system has plenty of other benefits. Those benefits will flow to people in rural areas as well as urban ones, to national security and international development, and to nature itself. To begin with, there are the health benefits of …

Community Benefit Agreements (CBAs) can provide tools for California communities negotiating offshore wind development impacts

Offshore wind is one of many renewable industries taking off in California as the state accelerates infrastructure investment and development to meet its climate targets. The California Energy Commission has adopted planning goals of 2-5 GW of offshore wind (OSW) by 2030 and 25 GW by 2045. Other state goals include reducing greenhouse gas emissions …

Mexico y el Cambio Climático

There is much to celebrate tomorrow on Cinco de Mayo. But probably not Mexican climate policy.

President Andrés Manuel López Obrador (generally known as AMLO) could be described as a left-leaning populist. Like other populist leaders, he has not been friendly to climate action. In November, Mexico ramped up its 2030 commitment under the Paris Agreement from 22% to 35%. That sounds like great news, but there may be less to …

Supreme Court Allows Major State, Local Government Climate Change Litigation to Proceed on Merits

Justices Decline to Intervene in Government Lawsuits Seeking Damages from Fossil Fuel Industry

This week the U.S. Supreme Court gave state and local governments a big–if preliminary–legal win against the fossil fuel industry.  The justices declined to take up numerous cases in which government entities have sued oil, gas and coal companies, seeking compensation for the climate change-related damage the jurisdictions they claim to have suffered, and which …

2150 and Beyond

Climate change’s long term effects on the planet will be profound.

Most climate change projections end at the end of this century. When the IPCC issued its first report, however, 2100 was  110 years  in the future. Looking that far ahead right now would bring us closer to 2150 than to 2100.  We’re only beginning to get a sense of the impacts of climate change that …

Can the New Climate Laws Transform our Transportation Infrastructure?

Flyer for Emmett Institute 2023 Symposium Panel 3: Transportation Case Study: Decarbonizing Planes, Trains, and Automobiles, listing Hilary Norton of California Transportation Commission and FAST, Beth Osborne of Transportation for America, and Regan Patterson of UCLA Engineering as panelists and Jonathan Zasloff of UCLA as moderator

The IIJA and IRA will spend a lot of money on transportation—but whether they’ll create fundamental change in our infrastructure or continue business as usual will depend on how that money is used.

This is the last in our series of posts previewing the Emmett Institute’s 2023 Symposium, coming up on April 12. Check out the first post, introducing some of the big questions around the IIJA and IRA, the second post, on transmission infrastructure, and RSVP for the Symposium here! Transportation is one of the most complicated …

The Social Cost of George W. Bush

Bush promised climate action but reversed himself. The result: billions of dollars in global harm.

When Bush ran for President in 2000, he endorsed mandatory limits on CO2 emissions.  Within three months of taking office, he reversed himself to the dismay of some members of his own administration.  The upshot was that the US resisted any effort to address climate change and embraced a “drill baby drill” energy policy. You …

Why the Bay Area’s Zero-Emission Appliance Rule is a Big Deal

BAAQMD’s trailblazing rule will ban the sale of new gas furnaces and water heaters to combat nitrogen oxide pollution. It marks a big victory for public health and the planet.

Air quality officials in the San Francisco Bay Area just made history by moving to adopt the nation’s first rules phasing out new gas-fueled water heaters and furnaces in homes and businesses within about eight years. This action serves as a major step in the effort to curb health-harming and planet-warming emissions from buildings. Several cities …
